Abstract: 1,133,569. Aminoalkyl - dihydro - ethano - anthracenes. CIBA Ltd. 12 Dec., 1966 [10 Dec., 1965], No. 55555/66. Addition to 947,943. Heading C2C. Novel aminoalkyl - dihydro - ethano - anthracenes of the formula in which alk represents a C 1-3  alkylene group and A is a mono- or di-C 1-5  alkylamino group, are obtained by selective reduction of group X to -alk-A in a compound of formula where X is as a group which on reduction forms -alk-A. Thus, X may be a group corresponding to -alk-A in which a methylene group adjacent the N atom is replaced by -CO-, and the reduction may be effected with LiAlH 4  or analogous amide-reducing agent. X may also be a group corresponding to -alk-A in which the N is linked to one of its substituents by a double bond, or in which one of the C atoms bound to N carries an OH. The reduction may be effected with a metal hydride, such as an alkali metal borohydride, or with hydrogen in the presence of platinum oxide or Raney nickel. Alternatively, 9 - oxoalkyl - 9,10 - dihydroethano - (1,2) - anthracene, e.g. the 9-formyl or 9-formylalkyl compound, may be reacted with an amine A-H under reducing conditions, or a compound with an -alk-NH 2  in the 9-position may be reacted with an aldehyde or ketone and reduced. # - [10 - Chloro - 9,10 - dihydro - 9,10 - ethano- (1,2) - 9 - anthryl] - propionic acid dimethylamide is obtained by reacting 10-chloro-9- anthraldehyde with NaBH 4  in ethanol to give 9 - hydroxymethyl - 10 - chloro - anthracene and reacting this with SOCl 2  to form 9-chloromethyl- 10-chloroanthraceme; refluxing the latter with malonic acid diethyl ester and NaH to form 1 - (10 - chloro - 9 - anthryl) - 2,2 - ethanodicarboxylic acid diethyl ester and boiling the latter with ethanolic NaOH then acidifying to yield the corresponding dicarboxylic acid; when heated to 220‹ this decarboxylates to #-[10-chloro-9- anthryl)-propionic acid which is heated with ethylene to form #--[10-chloro-9,10-dihydro-9,10- ethano - (1,2) - 9 - anthryl] - propionic acid; the acid is reacted with SOCl 2  to form the acid chloride which is reacted with dimethylamine to form the corresponding amide. N - acetyl - 9 - ethylaminomethyl - 10 - chloro- 9,10 - dihydro - 9,10 - ethano - (1,2) - anthracene is obtained by reacting 9-ethylaminomethyl-10- chloro - 9,10 - dihydro - 9,10 - ethano - (1,2)- anthracene with acetic anhydride. Pharmaceutical preparations which act against excitations of the central nervous system or may be used as tranquillizers in human or veterinary medicine comprise a compound of Formula I in admixture with a pharmaceutical carrier in forms suitable for enteral or parenteral administration. The compounds may be used in animal husbandry in the form of feedstuffs or feedstuff additives.

A sliver winding apparatus with downing and doffing means comprises a traversing bobbin frame 8 with a plurality of winding stations positioned one above the other and a rail-mounted trolley 17 movable towards and away from the frame 8 for supplying empty bobbins 13 (in position "a") and receiving fully wound bobbins (in movementbraking holder 59). The movable trolley 17 is provided with traversible carriages 19 with holders for the empty and fully wound bobbins. The carriages 19 are operatively connected to the frame 8 during the movement of the empty and fully wound bobbins. Each winding station comprises curved supporting slides 41, 42 for guiding the bobbins from supply position "a", to starting position "b", to winding-on position "c" where winding of an empty bobbin commences past a spring loaded flap 52 to a further winding position "d" where the main winding is performed, to a completed winding position "e". The bobbins are moved between these positions by rotary vanes 14. In operation, a sliver length counter (39) actuates a signal whereupon trolley 17 is moved manually or driven up to the frame 8 and is engaged therewith as shown in Fig. 1. Arm 57 then releases an empty bobbin 13 which moves from position "a" to position "b" to rest against one arm of the rotary vane 14. The vane 14 is rotated to move the vane into position "b" where serrated rubber driving elements on the bobbin 13 and driving drum 10 engage. Simultaneously, the other arm of vane 14 ejects a fully wound bobbin and the end of the sliver to be wound is engaged on card clothing on the empty bobbin and broken. The vane then moves the partially wound bobbin from position "b" to position "c". (For Figures see next page)

Abstract: 1,230,967. Labelling device. SOC. FRANCAISE D'ETIQUETAGE VIREY & GARNIER. 25 Feb., 1970 [19 Nov., 1969], No. 8961/70. Heading B8F. A device for transferring labels from a magazine past a gumming station to a bottle &c. comprises a transfer cylinder comprising a number of angularly adjacent segments 10 having a length corresponding to the label length disposed along generatrices of the cylinder surface, the segments being rotatable together and each fitted with a groove 11 registering the end 12 of a feeler 13 urged against the segment 10 by a spring (not shown), so that, when no label is present on the segment, a blade 20, actuated by the plunger 19 of an electro-mechanical device 14-18 controlled by the action of the feeler pressing against the segment, urges a roller 22 fitted to a rod 23, carried by the transfer cylinder, upwards towards a recess 24 of the segment, so that the roller 22 slidably engages a cam member 26 thereby forcing the segment 10 to recede towards the axis of rotation of the transfer cylinder and away from the gumming device. When a label is carried by the segment, the end 12 of the feeler is forced away from the segment and the device 14-18 allows the blade 20 to remain in its lowest position so that the roller 22 clears the cam 26 and gum is applied to the label. In an embodiment of a labelling machine, each segment is supported on a horizontal arm (40), Fig. 2 (not shown), extending laterally within the transfer cylinder and has its inner end mounted on a pivot pin (41), each arm being operatively connected to a roller (22) via a curved crank pin (42); the angular shift of the roller in relation to the pivot pin is calculated to ensure that the backward movement of the segment is parallel to the enveloping surface of the transfer cylinder. Labels are fed from packs (32) by reciprocating rollers (33) to the transfer cylinder. A belt (34) is constantly coated with adhesive; the belt applies the adhesive to the backs of the labels on the transfer cylinder, picks them up, and carries them to the turret (38) of the labelling machine.

Abstract: 1,231,098. Determining moment of inertia electrically. CARL SCHENCK MASCHINENFABRIK G.m.b.H. Oct 16, 1968 [Aug.10, 1968], No.49067/68. Heading G1N. [Also in Divisions G3 and H4] The moment of inertia of a test body is determined by mounting it on a spring-loaded table and causing it to oscillate about a desired axis at its natural frequency of vibration, using an electromagnetic pick-up and drive to provide a controlled oscillation amplitude, the frequency being a measure of the moment of inertia about the said axis. As shown, a pick-up 1 associated with the test body and mounting table assembly produces a signal proportional to angular velocity which after filtering and amplifying is fed to drive units 8. The pick-up signal is also integrated at 17, to determine angle of swing, and the positive and negative peak values of the swing angle are fed to capacitors 20, 21 via electronic switches 18, 19 controlled to operate when the angular velocity is zero, coinciding with the peak values of swing. The swing amplitude signals on capacitors 20, 21 are compared at 22 with a desired value, and any difference is made to vary the gain of the drive circuit to maintain a constant amplitude of swing. One of the switches 19 is associated with a counter 35 indicating the frequency of vibration, which is a measure of the moment of inertia. The signals may be monitored at various points in the network by a C.R.O.

Abstract: 1,258,145. Gunn effect devices. INTERNATIONAL BUSINESS MACHINES CORP. 14 Nov., 1969 [27 Dec., 1968], No. 55768/69. Heading H1K. A low threshold voltage Gunn effect device includes a semi-conductor body made of an alloy of first and second compounds. The energy gap EG between the valence and lowest energy conduction band valley of the first compound is less than the intervalley energy E D  between the lowest and next higher energy conduction valleys, while the EG of the second compound is greater than its E D  and also greater than the EG of the first compound. The proportions of the compounds are such that the EG of the alloy exceeds its E D  which in turn is at least 4 kT. Suitable alloys are Al x In 1-x Sb, InP x Sb 1-x , InP x As 1-x , Ga x In 1-x As, and Al x In 1-x As for appropriate values of x, but the preferred composition is Ga x In 1-x Sb where x lies in the range 0À35 to 0À9. For operation in the domain transit time mode, for high power, or when using a high load impedance with the device x must be between 0À35 and 0À5. With this alloy maximum difference in mobility between the two conduction valleys is achieved with the current path parallel to a 111 crystallographic axis. A horizontal zone-levelling technique for producing the alloy is described. Lapped and polished slices are provided with electrodes by evaporating tin containing 1% of tellurium on both faces, alloying in vacuo by focussing projection lamps on it and then electrolessly applying nickel between upper and lower electroplated gold layers. Single elements of various specified sizes are then cut from the slices.
